OPERATION
WARNING
Always position the unit on the operator’s right side. The use of the unit on the operator’s left side
will expose the user to hot surfaces and can result in possible burn injury.
WARNING
To avoid burns from hot surfaces, never operate unit with the bottom of the engine above waist
level.
WARNING
Always hold the string trimmer away from the body keeping clearance between the body and the
product. Any contact with the housing or string trimmer cutting head can result in burns and/or
other serious personal injury.
Hold the trimmer with your right hand on the rear handle and your left hand on the front handle.
Keep a rm grip with both hands while in operation. Trimmer should be held at a comfortable
position with the rear handle about hip height.
Cut tall grass from the top down. This will prevent grass from wrapping around the shaft housing

the string head, STOP THE MOTOR, disconnect the power cord, and remove grass.

OPERATION
• Avoid hot surfaces by always keeping the tool away from your body. (Proper operating position
shown in gure 6.)
• Keep the trimmer tilted toward the area being cut; this is the best cutting area.
• The trimmer cuts when passing the unit from right to left. This will avoid throwing debris at the
operator. Avoid cutting in the dangerous area shown in gure 7.
• Use the tip of string to do the cutting; do not force string head into uncut grass.
• Wire and picket fences cause extra string wear and breakage. Stone and brick walls, curbs,
and wood may wear string rapidly.
• Avoid trees and shrubs. Tree bark, wood moldings, siding, and fence posts can easily be
damaged by the string.
